From d4c003f5049e459f59b4c669a7b2b880b91b62b4 Mon Sep 17 00:00:00 2001 From: Pavan Nikhilesh Date: Tue, 16 Jan 2018 23:16:00 +0530 Subject: [PATCH] app/eventdev: launch pipeline lcores The event master lcore's test termination and the logic to print the mpps are common for the queue and all types queue test. Move them as the common function.
